Is there anything like this? Something like Roblox, but rather than using a central server, using a network of decentralised servers with different self-hosted instances (a bit like the fediverse, but for online multiplayer games)
If there’s nothing like this, how difficult would it be to start something like this myself?
edit: Or maybe something like Scratch, where you’re not tied to a specific movement system and can program whatever kind of game you want?
more like a platform where the community is able to publish user-created games for people to play. Maybe the different instances could be different types of games (e.g. action, RPG, puzzle) or different languages/regions. For instance, something like Roblox and even Scratch is where people are able to make their own games and make it public so others can play (though for Scratch, it’s not just games).
A program that covers all kinds of games is going to be challenging due to sheer variety there would be. You could build a specialised protocol for a specific genre of games, but I think at that point, it would make more sense to build your own game, and use Fediverse identity to identify the user.
